DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UCGEN/14/">U
 nderstanding symplectic fillings of contact manifolds via algebraic variet
 ies</a>\nby Bahar Acu (Northwestern University) as part of UCGEN - Uluslar
 arası Cebirsel GEometri Neşesi\n\n\nAbstract\nThis talk is an attempt fo
 r a (pandemic-conscious) invitation to contact topology via an algebro-ge
 ometric approach with the caveat that we admit having little to no under
 standing of many concepts in algebraic geometry. A very useful strategy 
 in studying topological manifolds is to factor them into smaller pieces.
  Briefly\, an "open book decomposition" on an $n$-dimensional manifold
  (the open book) is a type of fibration over a circle that helps us stud
 y our manifold in terms of its $(n-1)$-dimensional fibers (the pages) a
 nd $(n-2)$-dimensional boundary of these fibers (the binding). Open book
 s provide a natural framework for studying the topological properties of 
 a geometric phenomenon called "contact structures" on smooth manifolds
 . In this talk\, we aim to provide an exposition of results\, some of wh
 ich are fruits of several joint works\, concerning "symplectic fillings"
  of contact manifolds given by certain classes of algebraic varieties u
 sing their "supporting" open books.\n
